LIFT FOR WELL-DRILLING AND PUMPING RIGS.

SPECIFICATION forming part of Letters Patent No. 696,252, dated March 25, 1 902. Application filed April 13, 1901. Serial No. 55,600. (No model.)

To all whom, it ntcty concern:

Be it known that I, MICHAEL D. MOMANUS, a citizen of the United States of America, residing at Titusville, in the county of Crawford and State of Pennsylvania, have invented certain new and useful Improvements in Lifts for WVell-Drilling and Pumping Rigs; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to new anduseful improvements in a lift for well-drilling and pumping rigs.

The object is to provide a simple, practical, and convenient apparatus in connection with a rig for the purpose of raising andlowering bailers, sucker-rods, tubing, &c., into and out of wells.

I accomplish my objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a rig equipped with my improvements. Fig. 2 is a rear view of the lift mechanism, partly shown in section. Fig. 3 is a plan view of a portion of the same. Fig. 4 is an end elevation ofa portion thereof. Fig. 5 is an inner side view of one of the pillow-blocks to receive one of the clutch members. Fig. 6 is a side view'of the cap for said block. Fig. 7 is a side View of a Windlass having upon one side a portion of a clutch. Fig. 8 is a side view of the other clutch member.

In all views similar detail parts are designated by numerals of like character.

In said drawings, 1 indicates the rig; 2, the

bull-wheel; 3, the Samson-post; 4, the walking-beam, mounted upon said post; 5, the main shaft, carrying band-wheel 7 and crank 8. 9 is the pitman-rod, connecting said walking-beam with said crank, and 10 is the main cable, extending from bull-wheeldrum 11 to the top of rig and over pulley 12, all of such parts being old and well known in the art.

My improvements consist of providing one of the pillow-blocks 13 upon its inner side with an extended sleeve 14, having a shouldered portion 15, into which is formed a ball-race 16. This sleeve and block proper is preferably of one piece and is provided with a cap 17. Loosely mounted upon said blocksleeve is the Windlass 18, which is provided at one side with a ball race or groove 19, carrying balls 20, which engage or register with the race in the said sleeve. The halls are retained in the said Windlass-groove by a ring 21. On the opposite side of said Windlass is found or secured an annular flange or clutch member 22, which tapers inwardly.

A staple 23 is attached to the base of the rig, and to this staple is secured a band 24, which passes upwardly around the periphery of the clutch member 22. This strap is attached to a rod 25, which extends forward to or near the center of the rig to a convenient point. To the rig-post is attached a small plate or keeper 26 to engage the teeth 27 of said rod.

Rotatably mounted upon the main shaft between the band-wheel and Windlass is the clutch member 28. This portion of the clutch is attached to the shaft by means of a key 28 to permit longitudinal adjustment thereof. A groove 29 is formed around the base of this clutch member, into whichis fitted the strap 30 of the lever 31. This lever is pivoted at its lower end to a post 32 and is connected at its upper end to the long lever 33. This lever 33 is pivoted to a post 34 and extends forward to a convenient place near the center of the rig and engages with a toothed rack 35. Attached at one end to the said Windlass is a rope or line 36, which passes downwardly under the pulley-wheel 37, upwardly and over the pulley 38 at the top of the rig, and thence downwardly in position for lifting. Power being transmitted to the band-wheel by means of a belt 39, the walking-beam is set in motion for drilling. Now when it is desired to elevate or lower bailers, tubing, sucker-rods,

&c., attached to the line 36 the rod 25 is disengaged from rack 26 andpushed rearward toslacken the friction-band 24. The rod 33 is then operated to throw the clutch member '28 into engagement with the clutch portion suflicient to rotate the Windlass, the speed of which may be regulated as desired by slacking the friction-band 24. The object of the antifriction-balls is to dispense with friction between the outer face of the Windlass and bearing when the clutch member 28 is thrust into engagement with the other member.

This invention is a distinct apparatus from that used in drilling and, as before stated, is intended only for use with bailers, tubing, sucker-rods, the.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the band-wheel shaft and apillow-block of awell-drilling and pumpingrig,and aclutch member keyed upon said shaftand having means for movingitslidably thereon, of a sleeve projecting from said pillow-block and inclosing said shaft, said sleeve having a head at one end, a Windlass loosely mounted on said sleeve and formed relatively thereto to provide a ball-race between it and said shoulder, balls confined in said race to take the side thrust of said windlass,a clutch member carried by said Windlass, a brake acting upon said clutch-member, and means for connecting the Windlass with the device to be raised and lowered thereby.

2. A well-drilling and pumping rig, comprising in combination with the band-wheel shaft thereof, a slidable clutch member keyed upon said shaft, a lever pivoted at one end at one side of said shaft and engaged between its ends with said clutch member, a lever pivoted between its ends and having one extremit-y pivoted to the first lever, a sleeve encircling said shaft and having a head at one end, a Windlass loosely mounted on said sleeve and formed relatively thereto to provide a ballraee between it and said head, balls confined in said race to take the side thrust of said windlass, a clutch member projecting directly from said Windlass, to be engaged by the first-mentioned clutch member, a brake mechanism for the second-mentioned clutch member, said brake mechanism having a lever for controlling the same, and means for connecting the Windlass with the device to be raised and lowered thereby, substantially as described and for the purposes set forth.

In testimony whereof I have hereunto atfixed my signature in the presence of two subscribing witnesses.

MICHAEL l MCMANUS.
